my 98 has 6CTA CPL 2172, it is a 450hp version.. I dont think it made a 407 hp version, maybe ask for the engine serial number? The 6CTA is a best of an engine, wet sleeve cylinders, 6 in line and easy to work on. If you look at the test results on these engines, the 3500 express can reach 30+ knots at full rpm.
